People define human beings as "the sign making animal". I think that is a bit species-ist. Animals clearly have the ability to communicate using sounds and gestures. What distinguishes us, I believe, is the fact that we have mastered fire. We are a "fire-making animal" and that creates a number of attendant responsibilities and drives to civilization. I recently read an interesting interpretation of the symbol of the cross--namely, that it symbolizes the ancient human ability to generate fire by rubbing two sticks together. I think it is reasonable, when considering the enormous evolutionary advance that the mastery of fire has brought about, to speak of the "fires of the mind".
Chomsky is a thinker who is very interested in mind-control, how human minds are manipulated so that thoughts do not become too "conflagratory" and he notes that violence is extremely effective in achieving its aims. He also notes that terrorism is the weapon of the strong. It is an extravagant mystery, (I'm using a phrase from Heart Of Darkness) that in spite of recognizing how effective violence is in achieving political ends, as far as I know Chomsky does not endorse it as a means to achieve the political ends that he supports, like amnesty. I would suggest that Chomsky's world view regarding mind control is a projection of his own aggressive attempt to control the fires of his own mind but it happens to be the right world view. Just because you're paranoid doesn't mean that people aren't against you. It seems that Chomsky, ironically, is true to the real meaning of jihad, namely using such violence as you feel to struggle to master yourself.
Is violence inevitable? According to New Scientist,it's not love, affection or even blatant self-interest that is at work in human cooperation - it's anger. Nevertheless, this does not mean, in my view, that we are no better than apes. Violence is always with us but I think it can be sublimated into civilization and the growth of new forms. To give an example, I encountered some research where apes had been taught to recognize the first few numbers, say, from 1 to 6. An experiment was done where two dishes of sweets were placed in front of the ape, one with more sweets than the other. The rule the experimenter was applying was that the ape always got the dish other than the one it chose. The apes were unable to learn the rule and became extremely distressed when they always tried to grasp the dish with more sweets but ended up with the dish containing fewer. However, when the sweets on the dishes were replaced by the corresponding number, the apes were suddenly able to learn the rule and choose the smaller number in order to get more sweets. This kind of liberation through number is what I mean when I say that we can sublimate our selfish, grasping instinct to violence and use it to drive forward the frontiers of knowledge in academic pursuits, in which Chomsky is exemplary.
